Weather Analysis & Predictability

The science of analysis and prediction of large-scale systems, such as extratropical cyclones and their associated fronts and jet streams, has recently advanced with the utility of numerical weather models and ensemble forecasts. The prediction of atmospheric phenomena that traditionally have been difficult to forecast accurately, such as precipitation amount and type, can be vastly improved by running several numerical forecasts starting from slightly different initial states and/or different model formulations. Other current focus areas include examining the mechanisms of North American Monsoon onset and maintenance, with the long-term goal of providing useful seasonal predictions of summertime precipitation over the region.
